Its story

In southern Centaurus pulses a blue-white B-class star whose light set out around 1543, just as Copernicus was publishing De revolutionibus and unseating Earth from its pedestal. It is a variable: its brightness breathes, rising and falling in slow cycles, as if the star itself were beating. Far hotter and more massive than the Sun, it reminds us that the universe is a body in constant pulse, not a fixed postcard against a black backdrop.
